BUFFER FOR 'VESSELS Specification of Letters Patent.

Application led April 15, 1913.

Patented Feb. 3,1914. serial No. 761,401.

To all 'whom t may concern: I

Be it known that I, JOSEPH KRLIK, a subject of the King of I-Iungary,residing at Belleville, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements in Buffersfor Vessels, of which the following is a specification.

This invention relates to buffers for vessels, and the primary object ofmy invention is to provide the bow of various kinds of vessels and boatswith novel buffers that will prevent the bow of a boat from beingcrushed or injured by contacting with icebergs, floating debris, wharvesand vessels.

Another object of this invention is to provide the bow of a vessel witha plow or deflector that wards 0E ice-bergs and floating debris to thatextent as not to retard progress of a vessel.

A further object of this invention is to provide simple, inexpensive anddurable buffers for the bow of a vessel that occupy a comparativelysmall space and do not in-. terfere with the general operating mechanismof the vessel.

lith the above and other objects in View the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure l is a sideelevation of a portion of a vessel provided with the buffers, and Fig. 2is a horizontalsectional view of the same.

Further describing my invention in detail with reference to the drawing,wherein like numerals denote corresponding parts throughout: l denotesthe hull of a vessel having the bow 2 thereof provided with a pluralityof vertical parallel uprights or bearings 3 and slidably mounted inthese uprights are buier rods 4. The rods l eX- tend through bearings 5,secured, as at 6, to the bow of the vessel. The buffer rods 4 have theinner ends thereof provided with collars 7 and the outer ends withbuffer heads S that are made of a yieldable material, as hard rubber.The hard rubber is preferably set in the outer ends of the rods 4 and inlieu of hard rubber I can use wood or a material softer than the bow ofthe vessel.

The buffer rods e between the uprights 3 are provided with collars 9 andencircling said rods, between the uprights 3 and the collars 9 arecoiled compression springs 10. The tension of these springs issuliicient to hold the collars in engagement with the uprights, butwhenthe buffer heads 8 encounter an obstruction the buffer rods yield andfurther compress the springs 10 In practice it is preferable to arrangethe buffers one above the other with the uppermost buffer of greaterlength than the lower buffer, whereby the upper buffer will be broughtinto action first.

Associated with the buffers is a plow or defiector l1 that is riveted orotherwise connected, as at l2 to the bow of a vessel below the lowermostbuffer, this plow or deflector warding off such floating matter thatcannot be controlled by the buffers.

t is obvious that additional buffers can be located on the sides of thevessel, at the'- bow thereof or at such places throughout the vesselthat are liable to be injured by collision.

What I claim is l. The combination with the hull of a vessel, of aseries of vertically disposed parallel uprights arranged in andcentrally of the bow thereof, a pair of vertically alining bearingssecured to the outer side of the bow centrally thereof, superposedbuffer rods slidably mounted in said bearings and uprights and havingtheir outer ends provided with heads, the head of the upper rod beingnormally projecting beyond the head of the lower rod, spaced collarssecured to said buffer rods capable of engaging said uprights to arrestoutward movement of said rods, and independent coiled compressionspringsencircling said buffer rods between said collars and uprights fornormally maintaining the buffer rods projected.

2. The combination with the hull of a vessel, of a series of verticallydisposed parallel uprights arranged in and centrally of the bow thereof,a pair of vertically alining bearings secured to the outer side of the.fbew centrally thereof, superposed buffer rods slidably mounted in saidbearings and uprights and having their outer ends provided with heads,the head of the upper rod being normally projecting beyond the head ofthe lower rod, spaced collars secured to said buffer rods capable ofengaging said uprights to arrest outward movement of said rods,independent coiled compression In testimony whereof I afix my signaturesprings encirolng sailcl blier rods between in presence of twoWitnesses.

said collars an u ri ts ornormall Inainw f taining the buffr odsprojeeted,yand a JOSEPH KhALk' .5 downwardly inclined plow arrangedbelow Witnesses:
